The price on a brand new EMF '92 starts at around $320, so why bother converting a '94? Or, if none of the EMF offerings are to your liking, there are plenty of other short, light '92 rifles and carbines available in all sorts of chamberings, and very reasonable prices. The time, cost, and trouble of converting, along with the chance that the resulting rifle may not be reliable with shorter rounds that have different rim and head dimensions, well, I'd just pick up a new rifle.
